title: Bis[μ-3,5-bis-(pyridin-2-yl)pyrazolato]bis-[(hexa-fluoro-phosphato)copper(II)].
abstract: The title dinuclear complex mol-ecule, [Cu2(C13H9N4)2(PF6)2], lies about an inversion center. The Cu(II) atom shows a square-pyramidal coordination geometry with the basal plane formed by four N atoms of the two bis-chelating 3,5-bis-(pyridin-2-yl)pyrazolate ions and with one F atom of the hexa-fluoro-phosphate ion in the apical position. Mol-ecules are stacked in a column along the a axis through C-H⋯F hydrogen bonds. The columns are further linked by other C-H⋯F hydrogen bonds, forming a three-dimensional network.
